The 2016 Ethiopian Demographic and Health Survey (EDHS) report revealed that 67 children per 1000 live births died before the fifth birthday. This study aimed at determining factors affecting under-five mortality in Ethiopia using EDHS, 2016.Materials and Methods: The data were retrieved from the EDHS 2016, and a total weighted number of 11,023 under-five children were included. Descriptive statistics were reported using tables, graphs, and texts. A multilevel negative binomial regression model was fitted, and adjusted incidence rate (ARR) with a 95% confidence interval (CI) and a p-value < 0.05 were reported. The deviance test was used to check the goodness of fit.Results: Mother attained higher education (ARR=0.25, 95% CI: 0.10– 0.66), female-headed household (ARR=1.32, 95% CI: 1.05– 1.66), age of household head (AIRR=1.07, 95% CI: 1.03,1.11), preceding birth interval ≥ 48 months (ARR=0.51, 95% CI: 0.42– 0.61), child who had history of diarrhea (ARR=1.23, 95% CI: 1.08– 1.41), multiple birth type (ARR=1.80, 95% CI: 1.34– 2.42), mothers who delivered in health facility (ARR=0.86, 95% CI: 0.73,0.94), residents of Addis Ababa (ARR=0.52, 95% CI: 0.28– 0.98), and Amhara region (ARR=1.43, 95% CI: 1.09, 1.88) were statistically significant with the number of under-five mortality.Conclusion: In this study, under-five mortality remains a public health problem in Ethiopia. Educational status of the mother, women delivered at health institution, preceding birth interval 24– 35 and ≥ 48, and residents of Addis Ababa reduced the incidence of under-five mortality. On the other hand, being a female household head, age of mother at first giving birth, being employed, having multiple births, and childhood diarrhea were associated with a higher incidence of under-five mortality. This finding suggests that enhancing opportunities to female education, addressing regional disparities, and encouraging mothers to deliver at health institutions will help to reduce the burden of under-five mortality.Keywords: under-five mortality, negative binomial, multilevel analysis, Ethiopia
